A iicauda filed tiara; 15,1917. ain no 155,696,

The prirnary object of thef provision of a gage ofmthe;classdescribed, which when applied insures a uniforrnplacing of thesheets to beprintedupon the platen so that the same will securean accu rate register of the printed matter with the marginal edges of the paper.

Another objectv of the invention}; the; provision. of 1. a gage which ,is read ly and;

quickly applied to the tympangsheetor top sheet by slittingthesame, and which after being inserted in said slit is-readily adjustable with relation to said slit.

A further object;of theginvention is the provision of a gage of the class described which may be. readily adjusted withinthe, slit of the top sheet and locked in its adjusted positions.

A further object of the invention is the provision of a guide or gage of the class described, which combines a longitudinally and vertically adjustable guide strip which is associated with the upper jaw of the guide, so that it may be moved longitudinally in order that the same may be drawn back when it is desired to use the press for close margin work.

A still further object of the invention is the provision of a construction whereby the forward end of the guide strip is adjustable through the forward end flange of the upper jaw for either thick or thin work, as in the case where the printing may be on cardboard.

A still further object of the invention is the provision of an article of the class'described which is of very simple construction thoroughly reliable and eflicient in its operation and inexpensive to manufacture.

With these and other objects in view, it is thought that the nature, purpose and operation of the device will be readily understood when the specification and claims are taken in c nnectioniwith the accompanying drawlngs of.,whichz ,Figure- 1 isa fragmentary, perspective view;of ftl16;plZtt6Il and ty npan sheet with the-guide as associated therewith.

Referring to the drawing by reference characters Arepresents the platen andyB thetympan sheet which is clamped thereon,- both; ofwhich are: of the ordinary construcr tion; Q designates a-slit which isfcutin the tympan sheet for the reception: of the guide 'or gage which comprises a loweraw 10,;ofa

substantially rectangular formation, and-an upper jaw ll whichis of similar configure;

tion flhe lower jaw 10; is provided with; oppositely disposed upstanding. ears 12 andi arranged in close proximity .tothe forward;

edgesarea plurality, ofpjopenings The upper jaw 11 is provided for the major portioniof its sidelengths. with ..the: down? wardly extending marginal side flange 15. A pin or rivet 16 movably associates the jaws for pivotal movement, said pin pass ing through the ears 12 and the side flanges 14 near the rear end of the device. Arranged on the under side of the flanges let and 15, near the forward end of the device are a series of depending pointed projections or teeth 17 which are adapted, upon contact of the jaws, to register with and enter the openings 13 in the lower jaw. Coiled about the rivet 16 and confined between the ears 12 is a spring 18, the legs ofwhich tend to normally exert pressure upon the jaws at the rear extremity thereof for the purpose of bringing the jaws at their forward end into contacting relation. Underlying the bottom face of the top jaw 11 is a guide strip 19, which is preferably of resilient material, said strip is guided at its rear end through abearing 20 which is stamped from the aw 11. The forward end of the guide strip is slightly upturned and extends through the U shaped slot 21, the branches of which are adapted to lock the strip in its several horizontal planes in order that the guide strip may be adjusted for thick or thin work.

n i ,e

in operation of the device, thelrear ends 01 the jaws are grasped hetween the lingers and manipulated to open the forward end ot the jaws, the lowe jaw 10 then inserted.

top jaw 11, forcing the teeth 1'? through the tyinpan sheet and into the openings 13 thus locking the gage to said sh et. li hen the work is of the close margin type the guide strip 19 may he moved longitudinally with the relation to the jaw 11, so that the end protruding through the slot- 21, may be brought closer to tl e flange 15 so as not to interfere with the a:tion of the type carrier. a further adjustment of the guide strip is provided for by providing the slot 21 shown, so that tie same may be engaged in the upper leg or oiiset of the slot 9i for thick work or the lower leg for thin work.

Having thus described the invention, it is thou ht that the device will he readil un-' derstood by those skilled in the art and a more extended description has been omitted.

l -fhat is claimed is 1. In combination with tyinpan sheet, having a slit therein or" a gage comprising a lower jaw, adapted to enter said slit and an upper jaw pivoted thereto, having a marginal f ange depending therefrom, teeth on the lower edge of said flange, registering openings adjacent the edges of the lower @opies DI.

pressure is brought to hear on the ited to receive id teeth, nieans ioi norina r forcing the togeth r and guide strip interposed between said jaws, said strip being adj stable vertically' and longitudinally.

in combination with a tynipan sheet, having a slit therein of a gage comprising a lower jaw, adapte upper jaw pivote hereto, having a man g'oal flange depending tneretrorn, teeth on the lower edge of said flange, registering openings adjacem tie edges of the lower jaw, adapted rece' said teeth, means for normally forcing ti jaws together and a resilient longitud sl able guide strip it, interposed between said jaws, guided at its rear end in the upper jaw and adjustable vertically at its forward end.

3. in combination with a tynipan sheet, having a slit thereinot a gage comprising a lower jaw, adapted to enter said slit and an upper aw pivot d thereto, having a marginal flange depend therefrom, teeth on the'lower .ecge of said flange, registering openings adjacent the edges of the lower j aw,'adapted to receive said teeth, means for normally forcing the resilient longitudinal slidable guide strip aid jaws, guided at its jaw, and a slot in the e depending flange to rear in the upper torwarl receive the, forward end of said strip and ea d strip in its vertically ad usted positions within said slot.

in testimony whereof l aiiir my signature.
